Its been awhile sorry and there has been a huge amount of work done on top of my earlier work. Cannot debug that anymore and I am finding myself in the role of the old guy who just complains a lot. Some of that functionality seems bizarre to me like the on the fly conversion between huge pages and regular pages, weird and complex page count handling etc etc. The last time I looked at the code I was horrified to find that the new huge page migration does not use migration ptes to create a cooldown phase but directly swaps the pmd. That used to cause huge problems with regular pages in the past. But I was told that was all safe.
